About
Koji Masumori is a leading colorectal surgeon whose research has been instrumental in advancing robotic surgery for rectal and colorectal cancers. His work focuses on refining operative techniques, improving patient outcomes, and evaluating the comparative effectiveness of robotic platforms. Masumori’s major contributions include demonstrating the feasibility and benefits of robotic surgery in the narrow pelvic space, particularly for preserving sexual and urinary functions in male patients—a critical quality-of-life consideration. His most cited paper (43 citations) provides a comprehensive operative technique review, while his 2019 cohort study (21 citations) confirms favorable short- and long-term outcomes. Notably, Masumori has been at the forefront of evaluating next-generation systems, such as the hinotori™ surgical robot, showing its potential to reduce subcutaneous emphysema compared to the da Vinci system. His work on total proctocolectomy for ulcerative colitis with cancer further showcases his technical innovation. With a growing body of evidence supporting robotic approaches, Masumori’s research is shaping the future of minimally invasive colorectal surgery in Japan and beyond.
